To mark the centenary of the Battle of the Somme, the Sladmore Contemporary gallery in Mayfair will be hosting an exhibition by the photographer Jolyon Fenwick, titled The Zero Hour Panoramas, 100 Years On: Views from the Parapet of the Somme. Fenwick has captured the historic battle grounds as they are today but with hand-annotated notes on the events as they took place in 1916. There are 14 photographs in the poignant series; see a preview of some of them below.
